These special effect pigments allow for a visual response to changes in temperature. The pigments are composed of microcapsules that change color reversibly. When the temperature is raised to a specified temperature the pigment goes from colored to colorless. The color returns to the original color as the pigment is cooled down. The particle size of the thermochromic pigment for all products is <6 microns (97%). The color and temperature are selected by the user.
